Is 9 a factor of 729?

Here we will show you two different methods you can use to determine if 9 is a factor of 729.

The first method entails simply listing all factors of 729 and then seeing if 9 is one of them. The factors of 729 are 1, 3, 9, 27, 81, 243, and 729. Looking at the list, you see that 9 is on the list, and the answer to "Is 9 a factor of 729?" is therefore yes.

For the second and perhaps easier method, we divide 729 by 9 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 9 is a factor of 729. If the quotient is a fractional number, then 9 is not a factor of 729.

729 divided by 9 is 81 which is a whole number. Thus, once again, the answer to "Is 9 a factor of 729?" is yes.
